openplan-record

openplan-record is a skill for Claude Code, Codex from BANANASJIM/openplan-skill. It costs 106 tokens per session (829 once invoked), scanned A, original, MIT.

A documentation workflow for turning human goals and decisions into organized project records. It separates lasting preferences, project documentation, handoff notes, reviews, temporary briefs, observations, and open questions.

In plain words
What is it for?
It helps classify conversation and implementation results, choose where each piece of information belongs, and update durable memory or documentation.
Why use it?
It prevents an agent's guesses from being recorded as the user's actual intent and helps keep project knowledge in the right place.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

openplan-record scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

OpenPlan Record

Use this after $openplan-core when conversation, review, or implementation output needs to become durable memory or documentation.

Core Principle

Memory and docs represent the human goal/intent. Do not record agent guesses as the human goal/intent. If the source is not explicit, mark it as inference or pending confirmation.

Record Types

Type Purpose Lifetime Examples
Memory Standing human preference or operating constraint Long-lived, compact "Do not checkout without permission", "docs in Chinese"
Docs Project source of truth and rationale Long-lived, structured architecture, workflow, ADR, conventions
Handoff Cross-agent/session continuity Short/medium-lived current objective, blockers, next safe action
Review Evidence-backed quality finding Snapshot blocking issue, residual risk
HTML brief Temporary human frontend Disposable visual summary, teaching page

Update Flow

  1. Classify the information:
    • explicit human goal/intent;
    • agent observation;
    • evidence-backed project fact;
    • temporary session state;
    • unresolved question.
  2. Choose destination:
    • durable preference -> memory;
    • project rule/rationale -> docs;
    • current continuation state -> handoff;
    • quality issue -> review;
    • human-facing visualization -> HTML brief.
  3. Resolve destination root:
    • memory location from platform or user instruction;
    • docs root such as .openplan/, docs/, repo root, separate docs repo, or user-provided path;
    • temporary output path for disposable briefs.
  4. Preserve provenance:
    • source statement or artifact;
    • date/session when useful;
    • confidence;
    • scope.
  5. Deduplicate before adding.
  6. Mark stale or superseded entries instead of silently overwriting when history matters.
  7. Before changing durable goal/intent from ambiguous input, ask only if this agent is the human-facing coordinator; otherwise report Human decisions required.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
